| CheckpointResource | | public class CheckpointResource extends FramedResource implements Runnable(Code) | | A resource that will checkpoint the configuration at regular intervals.
This resource will make sure that current configuration is backed up to
disk at regular (configurable) intervals.
The webmaster can customize what part of the configuration is to be
backed up through boolean attributes.
|
| Method Summary | |
| public boolean | acceptUnload()
| | public synchronized void | activate()
Start the thread for this object, only if needed. | | public boolean | getFlushConfiguration()
Get the flush configuration flag. | | public boolean | getFlushLog()
Get the flush log flag. | | public boolean | getFlushProperties()
Get the flush properties flag. | | public int | getInterval()
Get the sync interval. | | public int | getPriority()
Get the priority for our attached thread. | | public boolean | getTraceFlag()
| | public void | initialize(Object values)
Activate the checkpointer at initialization time. | | public void | notifyUnload()
This resource is being unloaded.
Unloading that object will also stop the thread. | | public void | run()
We are attached a thread, now it's time to performt the job. | | protected synchronized void | stop()
Force our attached thread to stop. |
| ATTR_FLUSHCONFIG | | protected static int ATTR_FLUSHCONFIG(Code) | | Attribute index - Should we save the configuration ?
|
| ATTR_FLUSHLOG | | protected static int ATTR_FLUSHLOG(Code) | | Attribute index - Should we flush the logs too ?
|
| ATTR_FLUSHPROPS | | protected static int ATTR_FLUSHPROPS(Code) | | Attrbute index - Should we save the properties too ?
|
| ATTR_INTERVAL | | protected static int ATTR_INTERVAL(Code) | | Attribute index - Backup interval, in seconds.
|
| ATTR_PRIORITY | | protected static int ATTR_PRIORITY(Code) | | Attribute index - The priority of the flusher thread.
|
| ATTR_TRACE_CHECK | | protected static int ATTR_TRACE_CHECK(Code) | | Attribute index - should we display a trace when we perform checkpoint
|
| alive | | protected boolean alive(Code) | | Is our attached thread still alive ?
|
| checkpoint | | protected Date checkpoint(Code) | | Last date at which we checkpointed the configuration
|
| thread | | protected Thread thread(Code) | | Our thread, if one is currently attached.
|
| acceptUnload | | public boolean acceptUnload()(Code) | | This is the only resource that will refuse to be unloaded !
Always false. |
| activate | | public synchronized void activate()(Code) | | Start the thread for this object, only if needed.
|
| getFlushConfiguration | | public boolean getFlushConfiguration()(Code) | | Get the flush configuration flag.
A boolean, true oif the configuration is to beflushed at each interval, false otherwise. |
| getFlushLog | | public boolean getFlushLog()(Code) | | Get the flush log flag.
A boolean, true if the log is to be flushed at each refresh interval, false otherwise. |
| getFlushProperties | | public boolean getFlushProperties()(Code) | | Get the flush properties flag.
A boolean, true if the properties are to beflushed, false otherwise. |
| getInterval | | public int getInterval()(Code) | | Get the sync interval.
An integer number of seconds, or -1 if undefined. |
| getPriority | | public int getPriority()(Code) | | Get the priority for our attached thread.
An integer priority for the thread, which defaults to2 if undefined. |
| getTraceFlag | | public boolean getTraceFlag()(Code) | | |
| initialize | | public void initialize(Object values)(Code) | | Activate the checkpointer at initialization time.
|
| notifyUnload | | public void notifyUnload()(Code) | | This resource is being unloaded.
Unloading that object will also stop the thread. However, there is
a bug here, since if the resource gets unloaded for some reason, it
will not be able to wakeup itself at next checkpoint time.
|
| run | | public void run()(Code) | | We are attached a thread, now it's time to performt the job.
|
| stop | | protected synchronized void stop()(Code) | | Force our attached thread to stop.
